[0002] An environmental conditioning equipment can adjust the air in an indoor space through a refrigerant circulation system (such as a waterway system, etc.) with more than one indoor terminal device. During use, there may be a situation where different types of indoor terminal devices (such as fan coil terminals and radiant terminals, etc.) need to be turned on simultaneously.

[0003] During the operation of the environmental conditioning equipment, after the refrigerant absorbs energy, it can be transported to different indoor terminal devices. When different types of indoor terminal devices are turned on simultaneously, the temperature of the refrigerant flowing in is the same, while the demands of different types of indoor terminal devices are different, which results in the inability to effectively balance the demands of different types of indoor terminal devices.

[0054] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0055] An embodiment of the present invention provides an environment conditioning device for adjusting the air in an indoor environment.

[0056] In an embodiment of the present invention, referring to Figure 1 and Figure 2 , the environment conditioning device includes a control device 1, a heat pump system 2, and a coolant circulation system 3. The heat pump system 2 and the coolant circulation system 3 are both connected to the control device 1.

[0057] In this embodiment, the secondary refrigerant circulation system 3 is a water system, and the secondary refrigerant circulation system 3 can adjust the indoor temperature by using the indoor terminal equipment 31. In other embodiments, the secondary refrigerant circulation system 3 can also be a system that uses a secondary refrigerant to transfer energy, such as an ethanol solution, etc.

[0058] In this embodiment, the secondary refrigerant circulation system 3 includes a medium circulation loop and a liquid supply module 4. The medium circulation loop includes an energy supply module and at least two types of indoor terminal equipment 31. The liquid inlet of the indoor terminal equipment is connected to the liquid supply module 4. The liquid outlet of the energy supply module is connected to the indoor terminal equipment 31 and the liquid supply module 4.

[0059] The number of each type of indoor terminal equipment 31 among at least two types of indoor terminal equipment 31 can be one or more than one. At least two types of indoor terminal equipment 31 can be distributed in different indoor spaces. Alternatively, at least two types of indoor terminal equipment 31 can be arranged in different areas of the same indoor space.

[0060] In this embodiment, at least two types of indoor terminal equipment 31 are connected in parallel to the energy supply module. In other embodiments, at least two types of indoor terminal equipment 31 can be connected in series to the energy supply module.

[0061] In this embodiment, at least two indoor terminal equipment 31 of the same type are connected in parallel to the energy supply module. In other embodiments, at least two indoor terminal equipment 31 of the same type can be connected in series to the energy supply module.

[0062] In this embodiment, at least two types of indoor terminal equipment 31 include a first type of terminal and a second type of terminal. For example, the first type of terminal is a radiant terminal device (such as a radiant panel, a capillary tube network, etc.), and the second type of terminal is a convective heat exchange device (such as a fan coil unit, etc.). The radiant terminal device can be installed on the wall surface of the indoor space (including the wall surface and / or the ground surface, etc.).

[0063] The energy supply module is used to provide cold or heat for the flowing secondary refrigerant. The energy supply module can be a module for storing energy, such as a thermal energy storage water tank, etc. The energy supply module can also be a heat exchange module that is heat exchange connected to other systems with energy. The energy supply module can also be a module that can generate heat by itself, such as an electric heating module, etc.

[0064] The liquid inlet of each indoor terminal equipment 31 is communicated with the liquid outlet of the energy supply module, and the liquid outlet of each indoor terminal equipment 31 is communicated with the liquid inlet of the energy supply module. The secondary refrigerant can circulate between the indoor terminal equipment 31 and the energy supply module. When the secondary refrigerant flows through the energy supply module, it can absorb its cold or heat and release it to the indoor space where the indoor terminal equipment 31 is located.

[0065] Among at least two types of indoor terminal devices 31, the liquid inlet of the first type of terminal is connected to the liquid outlet of the liquid supply module 4. In this embodiment, at least two types of indoor terminal devices 31 include radiant terminal devices and other types of devices, and the liquid outlet of the liquid supply module 4 can be communicated with the liquid inlet of the radiant terminal device.

[0066] In this embodiment, the heat pump system 2 is an air source heat pump system. In other embodiments, the heat pump system 2 can also be a water source heat pump system, a ground source heat pump system, a dual-source heat pump system, etc.

[0067] In this embodiment, the heat pump system 2 includes a refrigerant circulation loop. The refrigerant circulation loop includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger. The second heat exchanger is heat-exchange connected to the energy supply module in the coolant circulation system 3. The second heat exchanger and the energy supply module can be a double-pipe heat exchanger or a plate heat exchanger.

[0068] The heat pump system 2 can have two operating modes: a refrigeration mode and a heating mode. When the heat pump system 2 operates in the refrigeration mode, the second heat exchanger is in an evaporation state to absorb heat. When the heat pump system 2 operates in the heating mode, the second heat exchanger is in a condensation state to release heat.

[0069] During the operation of the heat pump system 2, the coolant in the energy supply module can absorb the cold or heat released by the second heat exchanger. The coolant carrying cold or heat flowing out of the energy supply module can flow in the medium circulation loop to the indoor terminal device 31 to release the cold or heat into the air in the indoor space to adjust the environmental temperature of the indoor space. The coolant after releasing cold or heat can re-enter the energy supply module to exchange heat with the second heat exchanger, and the coolant after heat exchange can re-enter the medium circulation loop for heat exchange. In this way, the environmental control device can adjust the temperature of the indoor space.

[0070] When the heat pump system 2 operates in the refrigeration mode, the second heat exchanger is in an evaporation state. The coolant in the energy supply module absorbs the cold output by the second heat exchanger and then the temperature decreases to form a coolant carrying cold. The coolant carrying cold enters the medium circulation loop and flows to the indoor terminal device 31, releasing cold into the indoor space, and the environmental temperature of the indoor space decreases.

[0071] When the heat pump system 2 operates in the heating mode, the second heat exchanger is in a condensation state. The coolant in the energy supply module absorbs the heat output by the second heat exchanger and then the temperature increases to form a coolant carrying heat. The coolant carrying heat enters the medium circulation loop and flows to the indoor terminal device 31, releasing heat into the indoor space, and the environmental temperature of the indoor space increases.

[0072] The liquid supply module 4 is specifically a module that can be used to input coolant to the indoor terminal device 31. For example, the liquid supply module 4 includes at least two solenoid valves, a three-way valve, a mixing ratio valve, etc.

[0073] In this embodiment, the pipeline between the liquid outlet of the indoor terminal device 31 and the liquid inlet of the energy supply module is communicated with the liquid inlet of the liquid supply module 4. In this embodiment, the liquid outlet of the first type of terminal and / or the liquid outlet of the second type of terminal are communicated with the liquid inlet of the liquid supply module 4. In this embodiment, the liquid outlet of the radiant terminal device is communicated with the liquid inlet of the liquid supply module 4. In other embodiments, the liquid outlet of other terminal devices may also be communicated with the liquid inlet of the liquid supply module 4.

[0074] In other embodiments, the liquid inlet of the liquid supply module 4 may also be communicated with other modules that can provide the coolant outside the coolant circulation system 3.

[0075] The liquid supply module 4 can be opened or closed or the liquid outlet flow rate can be adjusted under the control of the control device 1. When the liquid supply module 4 is opened, it can supply liquid to the connected indoor terminal device 31; when the liquid supply module 4 is closed, it can stop supplying liquid to the connected indoor terminal device 31. Among them, when the temperature of the coolant output by the liquid supply module 4 is higher than the temperature of the coolant flowing out of the energy supply module, the temperature of the coolant flowing into the connected indoor terminal device 31 can be increased when the liquid supply module 4 is opened; when the temperature of the coolant output by the liquid supply module 4 is lower than the temperature of the coolant flowing out of the energy supply module, the temperature of the coolant flowing into the connected indoor terminal device 31 can be decreased when the liquid supply module 4 is opened.

[0076] In this embodiment, the pipeline between the liquid outlet of the energy supply module and the radiant terminal device is connected to the liquid outlet of the energy supply module. When the energy supply module operates in the first state, the liquid outlet of the energy supply module and the liquid outlet of the liquid supply module 4 are both communicated with the liquid inlet of the radiant terminal device. Then, the coolant flowing out of the energy supply module can be mixed with the coolant flowing out of the liquid supply module 4 and then flow into the radiant terminal device. At this time, the temperature of the coolant flowing into the radiant terminal device is higher than or lower than the temperature of the coolant flowing out of the energy supply module. When the energy supply module operates in the second state, the liquid outlet of the energy supply module is communicated with the liquid inlet of the radiant terminal device, the liquid outlet of the liquid supply module 4 is communicated with the liquid inlet of the radiant terminal device, and the liquid inlet of the radiant terminal device and the liquid outlet of the energy supply module are both blocked from the liquid outlet of the liquid supply module 4. At this time, the temperature of the coolant flowing into the radiant terminal device is equal to the temperature of the coolant flowing out of the energy supply module.

[0077] Furthermore, the refrigerant circulation system 3 also includes a fluid regulating module, which is connected to the control device 1. The fluid regulating module can be used to adjust the distribution, flow regulation and control of the supply and return liquid in the refrigerant circulation system 3. Specifically, the energy supply module and the indoor terminal device 31 are both connected to the fluid regulating module. In the present embodiment, the number of indoor terminal devices 31 is at least two, and at least two indoor terminal devices 31 and the energy supply module are both connected to the fluid regulating module. The fluid regulating module includes at least two fluid valves, which are connected to the indoor terminal devices 31 in a one-to-one correspondence, and the fluid valves are used to control the flow of the refrigerant of the corresponding indoor terminal device. In the present embodiment, the fluid regulating module is a manifold. In other embodiments, the fluid regulating module may also be a circulating pump.

[0078] Further, in this embodiment, referring to Figure 2 The control device 1 can also be connected to the environment detection module 5, which may include an indoor temperature sensor and / or an outdoor temperature sensor. The indoor temperature sensor can detect the ambient temperature of the indoor space regulated by the environment conditioning device; the outdoor temperature sensor can detect the ambient temperature of the outdoor space where the environment conditioning device is located.

[0079] Further, in this embodiment, referring to Figure 2 The control device 1 can also be connected to a temperature sensor 6, which is arranged on the surface of the indoor terminal device 31 or the wall on which the indoor terminal device 31 is installed, so as to detect the surface temperature of the indoor terminal device 31 or the temperature of the wall on which the indoor terminal device 31 is installed.

[0080] Further, in this embodiment, referring to Figure 2 The control device 1 can also be connected to a temperature detection module 7, which is arranged on the water inlet side of the radiation terminal device to detect the temperature of the refrigerant flowing out of the energy supply module and the refrigerant flowing out of the liquid supply module 4 after mixing.

[0081] In the embodiment of the present invention, refer to Figure 2 The control device 1 of the environment conditioning device includes: a processor 1001 (such as a CPU), a memory 1002, a timer 1003, etc. The various components in the control device 1 are connected via a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0082] Those skilled in the art will understand that Figure 2 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0083] As shown Figure 2 in the figure, the memory 1002 as a storage medium may include a control program for the environmental control device. In the Figure 2 device shown, the processor 1001 may be used to call the control program for the environmental control device stored in the memory 1002 and perform the relevant step operations of the control method for the environmental control device in the following embodiments.

[0084] An embodiment of the present invention also provides a control method for an environmental control device, which is applied to the above environmental control device.

[0085] Referring to Figure 3 , an embodiment of the control method for the environmental control device of the present application is proposed. In this embodiment, the environmental control device includes a heat pump system and a secondary refrigerant circulation system. The secondary refrigerant circulation system includes a medium circulation loop and a liquid supply module. The medium circulation loop includes an energy supply module and at least two types of indoor terminal devices. The liquid outlet of the energy supply module is connected to the indoor terminal devices and the liquid supply module. The heat pump system is heat exchange connected to the energy supply module. At least two types of the indoor terminal devices include a first type terminal and a second type terminal. The liquid inlet of the first type terminal is connected to the liquid supply module. The control method for the environmental control device includes:

[0086] Step S10, obtaining the demand information of the indoor terminal device and the type of the indoor terminal device. The demand information includes whether the indoor terminal device has a heat exchange demand and the required secondary refrigerant temperature of the indoor terminal device;

[0087] In this embodiment, the demand information of each indoor terminal device in the environmental control device is obtained.

[0088] Among them, the demand information can be determined according to the instruction input by the user or by monitoring the environmental state and / or human state in the indoor terminal device.

[0089] The heat exchange demand here includes a refrigeration demand or a heating demand.

[0090] The types of indoor terminal devices include a first type terminal or a second type terminal. In this embodiment, the first type terminal is a radiant terminal device, and the second type terminal is a convective terminal device.

[0091] The required temperature of the secondary refrigerant is specifically the target temperature that the secondary refrigerant of the indoor terminal equipment needs to reach when meeting the heat exchange requirements and reliability requirements of the corresponding indoor terminal equipment. In this embodiment, the required temperature of the secondary refrigerant is the target temperature of the secondary refrigerant flowing into the corresponding indoor terminal equipment. The required temperature of the secondary refrigerant of the target terminal equipment can be determined according to the user-set temperature or according to the data monitored by the monitoring module in the space where the radiant terminal equipment is located.

[0092] Step S20, when the indoor terminal equipment includes a target terminal equipment, and the target terminal equipment includes a first target terminal of the first type of terminal and a second target terminal of the second type of terminal, determine the first target temperature of the secondary refrigerant of the energy supply module according to the required temperature of the secondary refrigerant of the second target terminal; wherein, the target terminal equipment is the indoor terminal equipment with heat exchange requirements;

[0093] In this embodiment, the first target temperature of the secondary refrigerant is the target value of the liquid outlet temperature of the energy supply module. In other embodiments, the first target temperature of the secondary refrigerant may also be the target value of the liquid return temperature of the energy supply module, and so on.

[0094] In this embodiment, when the required temperature of the secondary refrigerant of the second target terminal is one, determine the required temperature of the secondary refrigerant of the second target terminal as the first target temperature of the secondary refrigerant. When the required temperature of the secondary refrigerant of the second target terminal is more than one, the first target temperature of the secondary refrigerant here can be determined according to the required temperatures of the secondary refrigerants of more than one second target terminal. Specifically, the maximum temperature or the minimum temperature or the average temperature of the required temperatures of the secondary refrigerants of more than one second target terminal can be determined as the first target temperature of the secondary refrigerant. For example, the first target temperature of the secondary refrigerant can be determined according to the required temperature of the secondary refrigerant of the target terminal equipment of the preset type. Or, in the cooling mode, take the maximum value of the required temperatures of the secondary refrigerants of all target terminal equipment as the first target temperature of the secondary refrigerant; in the heating mode, take the minimum value of the required temperatures of the secondary refrigerants of all target terminal equipment as the first target temperature of the secondary refrigerant.

[0095] Step S30, adjust the liquid supply module according to the required temperature of the secondary refrigerant of the first target terminal and / or the first target temperature of the secondary refrigerant;

[0096] Here, the opening degree of the liquid supply module can be adjusted according to the required temperature of the secondary refrigerant of the first target terminal and / or the first target temperature of the secondary refrigerant, or the liquid supply module can be controlled to be opened or closed according to the required temperature of the secondary refrigerant of the first target terminal and / or the first target temperature of the secondary refrigerant.

[0097] In one implementation, the target outlet temperature of the liquid supply module can be determined according to the required coolant temperature at the first target end and / or the first target coolant temperature, and the operation of the liquid supply module can be controlled according to the target outlet temperature. For example, the required coolant temperature at the first target end can be determined as the target outlet temperature, or the target correspondence relationship between the required coolant temperature at the first target end and the target outlet temperature can be obtained according to the first target coolant temperature. Different first target coolant temperatures correspond to different target correspondence relationships, and the target outlet temperature corresponding to the required coolant temperature at the first target end is determined based on this target correspondence relationship.

[0098] In another implementation, the target opening degree of the liquid supply module can be determined according to the relationship value between the required coolant temperature at the first target end and the first target coolant temperature, and the liquid supply module can be controlled to operate at the target opening degree. For example, the temperature difference value between the first target coolant temperature and the required coolant temperature is determined, and the target opening degree of the liquid supply module is determined according to the temperature difference value, and so on.

[0099] When the liquid supply module is turned on, the temperature of the coolant output by the liquid supply module is different from the temperature of the coolant flowing out of the energy supply module. The temperature of the coolant output by the liquid supply module can be higher or lower than the temperature of the coolant flowing out of the energy supply module. When the liquid supply module is turned on, the coolant can be input into the first target end connected thereto. Based on this, both the coolant flowing out of the energy supply module and the coolant flowing out of the liquid supply module can flow into the first target end, and the temperature of the coolant flowing into the first target end will be higher or lower than the temperature of the coolant flowing out of the energy supply module.

[0100] Step S40, controlling the operation of the heat pump system according to the first target coolant temperature.

[0101] In the refrigeration mode, the heat pump system can be controlled to operate in refrigeration to release cold to the energy supply module according to the first target coolant temperature; in the heating mode, the heat pump system can be controlled to operate in heating to release heat to the energy supply module according to the first target coolant temperature.

[0102] In this embodiment, the actual coolant temperature currently flowing out of the energy supply module is detected, and the operation of the heat pump system is controlled according to the temperature difference value between the actual coolant temperature and the first target coolant temperature, so that the temperature of the coolant flowing out of the energy supply module can reach the first target coolant temperature. Specifically, at least one of the compressor, throttling component, and fan corresponding to the heat exchanger in the heat pump system can be controlled according to the temperature difference value. For example, when the energy supply module is in the refrigeration state, when the temperature difference value is less than the first preset temperature difference, the operation frequency of the compressor in the heat pump system is controlled to decrease; when the temperature difference value is greater than the second preset temperature difference, the operation frequency of the compressor in the heat pump system is controlled to increase, where the first preset temperature difference is less than the second preset temperature difference.

[0103] The execution sequence between step S30 and step S40 here is not specifically limited. During the execution of step S30 and step S40, control the operation of the secondary refrigerant circulation system so that the secondary refrigerant absorbs the energy of the energy supply module and then flows to each of the target terminal devices. Specifically, control the circulation pump in the secondary refrigerant circulation system to start, and control the control valve corresponding to the target terminal device to open. When the circulation pump starts, it can drive the secondary refrigerant to circulate in the medium circulation loop. When the secondary refrigerant flows through the energy supply module, it can absorb the energy of the energy supply module. When the corresponding control valve opens, it flows into the corresponding target terminal device to release energy.

[0104] A control method for an environmental conditioning device proposed in an embodiment of the present invention. When it is determined through demand information that there are different types of target terminal devices with heat exchange requirements, the operation of the heat pump system is controlled by determining the first target secondary refrigerant temperature according to the required secondary refrigerant temperature of the second type of terminal with heat exchange requirements, and the liquid supply module is adjusted according to the required secondary refrigerant temperature and / or the first target secondary refrigerant temperature of the first type of terminal with heat exchange requirements. Based on this, it can be ensured that the refrigerant flowing into the second type of terminal from the energy supply module can meet its usage requirements, and at the same time, the refrigerant flowing into the first type of terminal from the energy supply module can also meet its usage requirements under the adjustment of the liquid supply module. Thus, the temperature of the secondary refrigerant flowing into different types of target terminal devices can be differentially set to adapt to their actual requirements, thereby improving the overall consideration effect of the requirements of each device when the environmental conditioning device uses different types of terminal devices simultaneously.

[0105] Further, based on the above embodiment, another embodiment of the control method for the environmental conditioning device of the present application is proposed. In this embodiment, the liquid outlet of the energy supply module is connected to the first type of terminal, the liquid supply module, and the second type of terminal. The liquid supply module is located upstream of the first type of terminal and is used to adjust the temperature of the secondary refrigerant flowing into the first type of terminal. The liquid outlet of the first type of terminal and / or the liquid outlet of the second type of terminal is connected to the liquid supply module. The step of adjusting the liquid supply module according to the required secondary refrigerant temperature of the first target terminal and / or the first target secondary refrigerant temperature includes:

[0106] Adjust the opening degree of the liquid supply module according to the required secondary refrigerant temperature of the first target terminal and / or the first target secondary refrigerant temperature.

[0107] In this embodiment, if the liquid supply module is a mixing ratio valve, then adjust the opening degree of the mixing ratio valve according to the required secondary refrigerant temperature of the first target terminal and / or the first target secondary refrigerant temperature.

[0108] When the liquid supply module is opened, the secondary refrigerant flowing out of the first target terminal and / or the secondary refrigerant flowing out of the second target terminal is mixed with the secondary refrigerant flowing out of the energy supply module and then flows into the radiant terminal device.

[0109] When the environmental control device operates in the refrigeration mode, the energy supply module is in the cooling state, the liquid inlet of the second target terminal is not connected to the liquid outlet of the liquid supply module, then the temperature of the coolant flowing into the second target terminal is the same as the temperature of the coolant flowing out of the energy supply module; the temperature of the coolant flowing out after heat exchange in the first target terminal and / or the second target terminal will be higher than the temperature of the coolant flowing out of the energy supply module. The relatively higher-temperature coolant is mixed with the coolant flowing out of the energy supply module and then flows into the first target terminal. The temperature of the coolant flowing into the first target terminal will be higher than the temperature of the coolant flowing out of the energy supply module, that is, the temperature of the coolant flowing into the first target terminal is higher than the temperature of the coolant flowing into the second target terminal.

[0110] When the environmental control device operates in the heating mode, the energy supply module is in the heating state, the liquid inlet of the second target terminal is not connected to the liquid outlet of the liquid supply module, then the temperature of the coolant flowing into the second target terminal is the same as the temperature of the coolant in the energy supply module; the temperature of the coolant flowing out after heat exchange in the first target terminal and / or the second target terminal will be lower than the temperature of the coolant flowing out of the energy supply module. The relatively lower-temperature coolant is mixed with the coolant flowing out of the energy supply module and then flows into the radiant terminal device. The temperature of the coolant flowing into the first target terminal will be lower than the temperature of the coolant flowing out of the energy supply module, that is, the temperature of the coolant flowing into the first target terminal is lower than the temperature of the coolant flowing into the second target terminal.

[0111] Adjusting the opening degree of the liquid supply module here includes the following methods: increasing the opening degree, decreasing the opening degree, maintaining the current opening degree, operating at a target opening degree, and so on.

[0112] In one implementation, the target outlet temperature of the liquid supply module is determined according to the required coolant temperature of the first target terminal, and the opening degree of the liquid supply module is adjusted according to the target outlet temperature.

[0113] In another implementation, the opening degree adjustment value is determined according to the temperature difference value between the required coolant temperature of the first target terminal and the first target coolant temperature, and the opening degree of the liquid supply module is controlled to be adjusted according to the opening degree adjustment value.

[0114] In yet another implementation, the target outlet temperature of the liquid supply module is determined according to the first target coolant temperature, and the opening degree of the liquid supply module is adjusted according to the target outlet temperature.

[0115] In this embodiment, through the above method, the accuracy of the opening degree regulation of the liquid supply module can be improved to ensure that the temperature of the coolant flowing into the first target end can accurately meet the requirements of the first target module. Among them, when the environmental conditioning equipment operates in the refrigeration mode, it can ensure the refrigeration effect of the second target end while preventing condensation on the first target end or in the space where the first target end is located; when the environmental conditioning equipment operates in the heating mode, it can ensure the heating effect of the second target end while preventing the first target end from cracking due to excessive temperature. Based on this, the heat exchange effect of each target end device can be realized while improving the operation reliability of the first target end.

[0116] Further, in this embodiment, the control method of the environmental conditioning equipment further includes: obtaining the temperature of the mixed liquid flowing out of the liquid supply module and / or the temperature of the return liquid flowing from the first target end into the liquid supply module; the step of adjusting the opening degree of the liquid supply module according to the required coolant temperature of the first target end and / or the first target coolant temperature further includes: adjusting the opening degree of the liquid supply module according to the required coolant temperature of the first target end and / or the first target coolant temperature, as well as the temperature of the mixed liquid and / or the temperature of the return liquid.

[0117] The temperature of the mixed liquid here can be specifically detected by the above temperature detection module. The temperature of the return liquid can be specifically detected by a temperature detection module between the liquid inlet of the liquid supply module and the liquid outlet of the first target end.

[0118] In this embodiment, a relationship parameter between the temperature of the mixed liquid and the required coolant temperature of the first target end is determined; the opening degree of the liquid supply module is adjusted according to the relationship parameter. The relationship parameter includes the magnitude relationship, temperature difference value, ratio, etc. between the temperature of the mixed liquid and the required coolant temperature of the first target end. The opening degree adjustment parameter or target opening degree of the liquid supply module is determined according to the quantitative relationship or magnitude relationship between the temperature of the mixed liquid and the required coolant temperature of the first target end, and the current opening degree of the liquid supply module is controlled to be adjusted according to the opening degree adjustment parameter, or the liquid supply module is controlled to adjust from the current opening degree to the target opening degree for operation.

[0119] In this embodiment, when the environmental conditioning device is in the cooling mode, if the temperature of the mixed liquid is greater than the required coolant temperature of the first target terminal, the supply module is controlled to reduce the opening degree to decrease the liquid inflow volume of the supply module; if the temperature of the mixed liquid is less than the required coolant temperature of the first target terminal, the supply module is controlled to increase the opening degree to increase the liquid inflow volume of the supply module. When the environmental conditioning device is in the heating mode, if the temperature of the mixed liquid is greater than the required coolant temperature of the first target terminal, the supply module is controlled to increase the opening degree to increase the liquid inflow volume of the supply module; if the temperature of the mixed liquid is less than the required coolant temperature of the first target terminal, the supply module is controlled to reduce the opening degree to decrease the liquid inflow volume of the supply module. Here, the liquid inflow volume specifically refers to the amount of coolant flowing into the supply module from the first target terminal and / or the second target terminal. The opening adjustment value during the process of increasing or decreasing the opening degree can be a preset fixed value or a value determined according to the actual operating conditions of the environmental conditioning device.

[0120] Further, the opening adjustment direction can be determined according to the relationship parameter between the temperature of the mixed liquid and the first required coolant temperature, the opening adjustment value can be determined according to the temperature of the return liquid and the first target coolant temperature, and the supply module is controlled to adjust the opening degree according to the opening adjustment direction and the opening adjustment value.

[0121] In this embodiment, through the above method, it is beneficial to improve the accuracy of the opening control of the supply module, thereby further ensuring that the temperature of the coolant flowing into the first target terminal can accurately meet its actual requirements such as heat exchange requirements and reliability requirements.

[0122] In other embodiments, the opening degree of the supply module can also be adjusted according to the temperature of the return liquid and the first target coolant temperature, or the opening degree of the supply module here can be adjusted according to the temperature difference values between any two of the temperature of the mixed liquid, the temperature of the return liquid, the first target coolant temperature, and the required coolant temperature of the first target terminal.

[0123] Further, in this embodiment, after the step of obtaining the demand information of the indoor terminal device, it further includes: when there is the target terminal device and all the types of the target terminal devices are the same, controlling the supply module to close.

[0124] When the supply module is closed, the communication pipeline between the liquid outlet of the energy supply module and the liquid inlet of the radiant terminal device is blocked from the liquid outlet of the supply module, and the inlet temperature of each target terminal device is the same as the outlet temperature of the energy supply module.

[0125] In this embodiment, through the above method, it is beneficial to ensure that when the same type of target terminal devices are used simultaneously, the heat exchange effects of each target terminal device can be effectively improved.

[0126] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In this embodiment, referring to Figure 4 , after step S40, it further includes:

[0127] Step S50, when a preset condition is satisfied, determine the second target coolant temperature of the energy supply module according to the required coolant temperature of the first target terminal, where the preset condition indicates that the first target terminal has a reliability risk;

[0128] The reliability risk here includes cracking risk, condensation risk, unknown risk, etc. The preset condition includes the target temperature range that the mixed liquid temperature needs to reach when the first target terminal has a reliability risk or the target relationship that needs to be reached with the target temperature.

[0129] In this embodiment, determine the required coolant temperature of the first target terminal as the second target coolant temperature.

[0130] Step S60, control the operation of the heat pump system according to the second target coolant temperature.

[0131] In the refrigeration mode, the heat pump system can be controlled to operate in refrigeration to release cold to the energy supply module according to the second target coolant temperature; in the heating mode, the heat pump system can be controlled to operate in heating to release heat to the energy supply module according to the second target coolant temperature.

[0132] Obtain the outlet temperature of the energy supply module, and control the operation of the heat pump system according to the outlet temperature and the second target coolant temperature. Specifically, the operating frequency of the compressor, and / or the opening degree of the throttling device, and / or the fan speed corresponding to the first heat exchanger in the heat pump system can be controlled according to the outlet temperature and the second target coolant temperature.

[0133] After step S40, when the environmental conditioning device does not meet the preset condition, the heat pump system can be controlled to operate at the first target coolant temperature.

[0134] In this embodiment, through the above method, it is beneficial to timely set the target coolant temperature of the energy supply module based on the required coolant temperature of the first target terminal when the first target terminal has a reliability risk and the risk cannot be reduced by the temperature adjustment effect of the liquid supply module, which is beneficial to effectively reducing the reliability risk problem of the first target terminal.

[0135] Further, in one implementation of this embodiment, when the heat pump system operates in the cooling mode, the preset conditions include that the temperature difference between the mixed liquid temperature currently flowing out of the liquid supply module and the target mixed liquid temperature is less than or equal to a first preset temperature difference, or the temperature difference between the mixed liquid temperature and the target mixed liquid temperature is less than or equal to the first preset temperature difference and lasts for a first duration, or the detection of the mixed liquid temperature fails. The temperature difference being less than or equal to the first preset temperature difference indicates that the temperature of the coolant flowing into the radiant terminal device is too low.

[0136] Further, in another implementation of this embodiment, when the heat pump system operates in the heating mode, the preset conditions include that the temperature difference between the mixed liquid temperature currently flowing out of the liquid supply module and the target mixed liquid temperature is greater than or equal to a second preset temperature difference, or the temperature difference between the mixed liquid temperature and the target mixed liquid temperature is greater than or equal to the second preset temperature difference and lasts for a second duration, or the detection of the mixed liquid temperature fails. The temperature difference being greater than or equal to the second preset temperature difference indicates that the temperature of the coolant flowing into the radiant terminal device is too high.

[0137] It should be noted that the temperature difference value here is specifically the calculation result obtained by subtracting the target mixed liquid temperature from the mixed liquid temperature. The failure of the mixed liquid temperature detection may be caused by the damage of the temperature detection module for detecting the mixed liquid temperature or the communication failure between the temperature detection module and the control device, etc. The target mixed liquid temperature may be a preset fixed value or determined according to the actual operating conditions of the radiant terminal device. The first preset temperature difference and / or the second preset temperature difference may be preset fixed temperature differences or determined according to the outlet temperature of the radiant terminal device.

[0138] In this embodiment, setting the preset conditions in the above manner is beneficial to improving the accurate identification of the reliability risk of the radiant terminal device.

[0139] Further, based on any of the above embodiments, the step of obtaining the required coolant temperature of the target terminal device includes: determining the corresponding required coolant temperature according to the indoor temperature and the corresponding indoor target temperature of the indoor space where the target terminal device is located; and / or determining the corresponding required coolant temperature according to the dew point temperature and the corresponding indoor terminal device temperature of the indoor space where the target terminal device is located.

[0140] The indoor terminal device temperature may include the coolant temperature of the target terminal device, the surface temperature of the target terminal device, the wall temperature of the wall where the target terminal device is installed, etc.

[0141] Among them, in the process of determining the corresponding required refrigerant temperature according to the indoor temperature and the corresponding indoor target temperature of the indoor space where the target terminal device is located, and determining the corresponding required refrigerant temperature according to the dew point temperature and the corresponding indoor terminal device temperature of the indoor space where the target terminal device is located, the first reference refrigerant temperature can be determined according to the indoor temperature and the corresponding indoor target temperature of the indoor space where the target terminal device is located, the second reference refrigerant temperature can be determined according to the dew point temperature and the corresponding indoor terminal device temperature of the indoor space where the target terminal device is located, and the corresponding required refrigerant temperature can be determined according to the first reference refrigerant temperature and the second reference refrigerant temperature. Alternatively, the corresponding required refrigerant temperature can be determined by combining the indoor temperature and the corresponding indoor target temperature of the indoor space where the target terminal device is located, and the dew point temperature and the corresponding indoor terminal device temperature of the indoor space where the target terminal device is located, and the corresponding required refrigerant temperature can be obtained through comprehensive calculation.

[0142] In this embodiment, determining the required refrigerant temperature according to the indoor temperature and the indoor target temperature is beneficial to ensuring that the determined required refrigerant temperature can accurately reflect the actual heat exchange requirements of the corresponding target terminal device. Determining the required refrigerant temperature according to the dew point temperature and the corresponding indoor terminal device temperature is beneficial to reducing the condensation risk of the corresponding target terminal device. Combining the indoor temperature, the indoor target temperature, the dew point temperature, and the indoor terminal device temperature to determine the required refrigerant temperature is beneficial to ensuring that the heat exchange requirements of the target terminal device are met while reducing the condensation risk.

[0143] Furthermore, in this embodiment, the steps of obtaining the required refrigerant temperature of the target terminal device include:

[0144] When the target terminal device is the first target terminal with a refrigeration demand, determine the corresponding required refrigerant temperature according to the indoor temperature and the corresponding indoor target temperature of the indoor space where the target terminal device is located, and according to the dew point temperature and the corresponding indoor terminal device temperature of the indoor space where the target terminal device is located;

[0145] When the target terminal device is the second target terminal with a refrigeration demand, or when the target terminal device has a heating demand, determine the corresponding required refrigerant temperature according to the indoor temperature and the corresponding indoor target temperature of the indoor space where the target terminal device is located.

[0146] In this embodiment, when the temperature of the secondary refrigerant flowing into the first target terminal such as the radiation terminal device is too low during the refrigeration process, the risk of condensation is relatively high. Therefore, the required secondary refrigerant temperature corresponding to the first target terminal such as the radiation terminal device that needs refrigeration is determined based on the indoor temperature, the indoor target temperature, the dew point temperature, and the indoor terminal device temperature, which is beneficial to reducing the condensation risk while meeting the heat exchange effect of the first target terminal such as the radiation terminal device; while the second target terminal such as the convective terminal device has a relatively low condensation risk during the refrigeration process or any type of terminal device has a relatively low condensation risk during the heating process. Therefore, determining the required secondary refrigerant temperature solely based on the indoor temperature and the indoor target temperature is beneficial to avoiding the limitation of the required secondary refrigerant temperature by anti-condensation and improving the heat exchange effect of the terminal device.

[0147] Further, in this embodiment, the step of determining the required secondary refrigerant temperature corresponding to the indoor temperature and the corresponding indoor target temperature of the indoor space where the target terminal device is located includes: when the target terminal device has a refrigeration demand and the temperature difference between the indoor temperature and the indoor target temperature is greater than a first preset value, reducing the currently required secondary refrigerant temperature of the target terminal device to obtain the corresponding required secondary refrigerant temperature; when the target terminal device has a refrigeration demand and the temperature difference between the indoor temperature and the indoor target temperature is less than or equal to the first preset value, increasing the currently required secondary refrigerant temperature of the target terminal device to obtain the corresponding required secondary refrigerant temperature.

[0148] The first preset value can be a preset fixed value or can be determined according to user-set parameters. In this embodiment, the first preset value is greater than 0.

[0149] The temperature difference between the indoor temperature and the indoor target temperature being greater than the first preset value indicates that the temperature of the corresponding indoor space is too high and deviates from user comfort; the temperature difference between the indoor temperature and the indoor target temperature being less than or equal to the first preset value indicates that the temperature of the corresponding indoor space is close to the user's comfortable state.

[0150] The currently required secondary refrigerant temperature of the target terminal device can be a preset fixed value or can be a value determined according to the actual operating conditions of the corresponding space before the current moment based on the actual operating conditions of the corresponding space before the current moment.

[0151] When reducing or increasing the currently required secondary refrigerant temperature of the target terminal device, it can be adjusted according to a preset fixed temperature adjustment value, or the temperature adjustment value can be determined according to the temperature difference between the indoor temperature and the indoor target temperature.

[0152] In this embodiment, through the above method, the required refrigerant temperature of the target terminal device can be dynamically adjusted according to the actual situation of the indoor space, so as to ensure the accuracy of the cooling capacity output by the heat pump system when controlling the operation of the heat pump system according to the target refrigerant temperature determined corresponding to the required refrigerant temperature, thereby ensuring the reliable operation of each target terminal device and improving the refrigeration effect of each target terminal device.

[0153] Further, in this embodiment, the step of determining the corresponding required refrigerant temperature according to the indoor temperature and the corresponding indoor target temperature of the indoor space with heat exchange requirements includes: when the target terminal device has a heating requirement and the temperature difference between the indoor target temperature and the indoor temperature is greater than a second preset value, increasing the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature; when the target terminal device has a heating requirement and the temperature difference between the indoor target temperature and the indoor temperature is less than or equal to the second preset value, decreasing the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature.

[0154] The second preset value can be a fixed value set in advance or can be determined according to user-set parameters. In this embodiment, the second preset value is greater than 0.

[0155] The temperature difference between the indoor target temperature and the indoor temperature being greater than the second preset value indicates that the temperature of the corresponding indoor space is too low and deviates from user comfort; the temperature difference between the indoor target temperature and the indoor temperature being less than or equal to the second preset value indicates that the temperature of the corresponding indoor space is close to the user's comfortable state.

[0156] The refrigerant temperature currently required by the target terminal device can be a fixed value set in advance or can be a value determined according to the actual working conditions of the corresponding space before the current moment before the current moment.

[0157] When decreasing or increasing the refrigerant temperature currently required by the target terminal device, it can be adjusted according to a fixed temperature adjustment value set in advance, or the temperature adjustment value can be determined according to the temperature difference between the indoor target temperature and the indoor temperature.

[0158] In this embodiment, through the above method, the required refrigerant temperature of the target terminal device can be dynamically adjusted according to the actual situation of the indoor space, so as to ensure the accuracy of the heat output by the heat pump system when controlling the operation of the heat pump system according to the target refrigerant temperature determined corresponding to the required refrigerant temperature, thereby ensuring the reliable operation of each target terminal device and improving the heating effect of each target terminal device.

[0159] Further, in this embodiment, the step of determining the corresponding required refrigerant temperature according to the dew point temperature of the indoor space where the target terminal device is located and the temperature of the corresponding indoor terminal device includes: when the target terminal device has a refrigeration demand and the temperature difference between the indoor terminal device temperature and the dew point temperature is greater than or equal to a third preset value, reducing the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature, or using the current refrigerant temperature of the target terminal device as the corresponding required refrigerant temperature. When the target terminal device has a refrigeration demand and the temperature difference between the indoor terminal device temperature and the dew point temperature is less than the third preset value, increasing the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature.

[0160] The third preset value can be a fixed value set in advance or can be determined according to user-set parameters. In this embodiment, the third preset value is less than or equal to 0.

[0161] The refrigerant temperature currently required by the target terminal device can be a fixed value set in advance or can be a value determined according to the actual operating conditions of the corresponding space before the current moment. In one implementation, when determining the required refrigerant temperature of the corresponding target terminal device by combining the indoor temperature, the indoor target temperature, the indoor terminal device temperature, and the dew point temperature, the required refrigerant temperature corresponding to the target terminal device determined by the above indoor temperature and indoor target temperature can be used as the refrigerant temperature currently required by the target terminal device here. Or, use the required refrigerant temperature determined by the indoor terminal device temperature and the dew point temperature here as the refrigerant temperature currently required by the target terminal device during the process of determining the required refrigerant temperature by combining the indoor temperature and the indoor target temperature.

[0162] When reducing or increasing the refrigerant temperature currently required by the target terminal device, it can be adjusted according to a fixed temperature adjustment value set in advance or can be adjusted by determining the temperature adjustment value according to the temperature difference between the indoor target temperature and the indoor temperature.

[0163] In this embodiment, by the above method, it is possible to adapt to the condensation risk of indoor spaces and / or indoor terminal devices such as radiant terminal devices to dynamically adjust the required refrigerant temperature of the target terminal device, so as to ensure the accuracy of the cooling capacity output by the heat pump system when controlling the operation of the heat pump system according to the target refrigerant temperature corresponding to the required refrigerant temperature, thereby ensuring the refrigeration effect of the target terminal device while reducing the condensation risk.

[0164] Further, in this embodiment, after the step of determining the required refrigerant temperature corresponding to the target terminal device, it further includes:

[0165] When the target terminal device has a refrigeration demand and the corresponding required coolant temperature is lower than the minimum temperature, update the required coolant temperature corresponding to the target terminal device to the minimum temperature; and / or,

[0166] When the target terminal device has a heating demand and the corresponding required coolant temperature is higher than the maximum temperature, update the required coolant temperature corresponding to the target terminal device to the maximum temperature;

[0167] Wherein, the minimum temperature when the target terminal device is a convective heat exchange device is lower than the minimum temperature when the target terminal device is a radiant terminal device, and the maximum temperature when the target terminal device is a convective heat exchange device is higher than the maximum temperature when the target terminal device is a radiant terminal device.

[0168] Based on this, when the convective heat exchange device and the radiant terminal device are operating simultaneously, the heat exchange effect of the convective terminal device is effectively improved while the operating reliability of the radiant terminal device is effectively improved.
